How to parse XML and get instances of a particular node attribute?

You can use the xml library in Python to parse XML and get instances of a particular node attribute. Here's an example of how to do it:

import xml.etree.ElementTree as ET

# parse XML file
tree = ET.parse("file.xml")
root = tree.getroot()

# find all instances of a particular node attribute
for elem in root.iter():
    if 'attribute_name' in elem.attrib:
        print(elem.attrib['attribute_name'])

This code will parse an XML file named "file.xml" and find all instances of an attribute named "attribute_name". You can replace "attribute_name" with the actual name of the attribute you want to search for.
